Location:
Indian Springs is located on YMCA property and is
used as a camp during the summer months. Indian Springs is located just west
of Wakulla Springs State Park on Hwy 267.

Description:
Indian has a large cavern that funnels into a cave.
In November of 1991, the spring suddenly reversed flow. This caused the cave
entrance to plug up with sand, trapping a team of divers. The Aquacorp archives
(here)
has a detailed incident report by team member Bill Gavin. To date,
Parker's death is the only known fatality to occur that was not a direct result
of diver error. Until his death, he was the director of the WKPP. Later, George
Irvine would take up the position and restructure the team. He holds several
world records including furthest penetration from any air supply (19,000 feet
Wakulla Springs) as well as longest traverse between two entrances (Leon Sinks
system). The property to closed except to permitted groups and only during non-summer
months. The WKPP continues to do numerous explorations here in their attempts
to connect other area systems (such as Sally Ward and Wakulla Springs). There
are several videos in Real Player formatof the cave on Herve Deschamps's site
here.
Steve Auer has a good picture of one of the rooms in Indian Springs
